Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...

Due to their excellent properties, polymides (PIs) result promising as high-performance materials in different technological fields. In this research, both micron-sized tubular mesoporous silica (mSiO2) and double-tube diatomite particles with cadmium sulfide quantum dots are prepared by chemical deposition method. A cluster of type fluorescent is self-assembling carbon (CDs) on the inner surfa...

In this study, the DNA sorption performance of diatomite-Zn(II) embedded supermacroporous monolithic p(HEMA) cryogels were investigated for the purpose of designing a novel adsorbent that can be utilized for DNA purification, separation and immunoadsorption studies such as removal of anti-dsDNA antibodies from systemic lupus erythematosus (SLE) patient plasma. Poly(2-hydroxyethyl methacrylate) ...

This work investigated the feasibility of treating micro-polluted surface water for drinking water production with a bio-diatomite dynamic membrane reactor (BDDMR) at lab-scale in continuous-flow mode. Results indicate that the BDDMR was effective in removing COD(Mn), DOC, UV(254), NH(3)-N and trihalomethanes' formation potential (THMFP) at a hydraulic retention time (HRT) of 3.5h due to its hi...

In this work, a new nano-Bi₂MoO₆/diatomite composite photocatalyst was successfully synthesized by a facile solvothermal method. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-vis diffuse reflection spectroscopy (DRS) were employed to investigate the morphology, crystal structure, and optical properties. It was shown that nano...

BACKGROUND The 3,4-dihydroxy phenyl L-alanine (L-dopa) is a drug of choice for Parkinson's disease, controlling changes in energy metabolism enzymes of the myocardium following neurogenic injury. Aspergillus oryzae is commonly used for L-dopa production; however, potential improvements in ease of handling, growth rate and environmental impact have led to an interest in exploiting alternative ye...

osting by E Abstract A simple spectrophotometric method was developed for the simultaneous determination of five commercial cationic dyes at 2.0 8.5 lg L 1 level after using diatomite as solid-phase extractant. The method is based on preconcentration of the five dyes on natural diatomite solid-phase extractant and on multivariate calibration using partial least squares method (PLS-1). Compared ...

Diatomite-supported/unsupported magnetite nanoparticles were prepared by co-precipitation and hydrosol methods, and characterized by X-ray diffraction, nitrogen adsorption, elemental analysis, differential scanning calorimetry, transmission electron microscopy and X-ray photoelectron spectroscopy. The average sizes of the unsupported and supported magnetite nanoparticles are around 25 and 15 nm...

Polystrate fossils are one of numerous evidences for the rapid deposition of strata, as opposed to the uniformitarian belief in slow deposition over millions of years. They are briefly described from the Joggins Formation, Nova Scotia; Yellowstone National Park, Montana and Wyoming; Ginkgo Petrified Forest State Park, Washington; the Geodetic Hills of Axel Heiberg Island; the Lompoc diatomite, ...

Diatomite is a powdering mineral mainly composed of diatom microfossils present in marine and lacustrine soils, which influences their physical mechanical properties. Although many articles have been found the literature concerning influence diatomite overall behavior natural few research efforts carried out to evaluate microfossil species on shear resistance. Therefore, this research, content ...
